The upcoming Gundam Musou 3 (PS3/Xbox360) is schedule for a Dec. 6th, 2010 release (Price: 7800 Yen)...just in time for the holiday season. The game will be introducing some new game mechanics:

Partner Strike - When an area with an outpost base is conquered, the partner gauge will increase, Once the gauge hits maximum, hit the R2 button, and you can call in an allied mobile suit to bring in extra fire power. There will be 50 selectable allies to call in.Examples of support attacks
Wing Gundam Zero - Launches a heavy beam attack
Gundam Mk-II - Bazooka attack
Psycho Gundam - Makes a wide-range explosion attack* Images below shows the player playing as God Gundam (ahem...I mean Burning Gundam).. calling in a Partner Strike-to with an allied Psycho Gundam. Yes, even mobile armors can be called in. Pretty cool...

Catapult - Gain control of a catapult area and you can send your mobile suit to another map area quickly. Taking control of a catapult will give players an added tactical advantage!

* Images below shows the player piloting the Unicorn Gundam capturing a catapult and launching to another map in the game level. Just imagine how fun this would in multi-player games. I can't wait.

Emergency Dash - Execute an emergency dash to avoid the enemy's attacks. Player can also perform an emergency dash during a combo string.

Combat Offset - Basicallly means when two ace pilots clash in combat. When this happens the player will have to press the buttons labeled on the screen as fast as possible to make the bar fill up faster than your opponents. If succesfully performed, a special attack animation will occured for the winning side.
